Its like Linus Torvalds (inventor of Linux) said a few years ago.Most active OpenSource Projects are
less then 5 People and a lot are inactive or abandoned.Of course, there are a few wxceptions like Apache or Linux.

I think we need to join forces.
Nobody can do all Development work allone.
Right now hMailServer has 250.000 Lines of code, most of it C/C++, the rest C# and SQL-Scripts plus Installer scripting. I think we could attract more OpenSource Developers if hMailServer runs also on Linux because most OpenSource Developers are active on Linux or some flavor of **nix.
